this is what I do:
- With the pipe away from my face, I take a moderately deep breath.
- I put the pipe to my lips and draw as if I were drinking from a straw, letting the smoke fill my mouth. DO NOTE: I draw very gently, as if I were sipping tequila instead of a milk shake. If you draw strongly you'll burn your mouth.
- After I finish drawing, I take the pipe away from my mouth and at the same time I exhale the air I breathed in in Step 1, to force any smoke that is trying to come down back up: this keeps me from inhaling it.
- I swish the smoke around in my mouth making pumping motions with my cheeck muscles. Sometimes, this causes some smoke to go up to my nose via the upper airways: this is what is known as 'retrohaling' or 'snorking'.
- I blow the smoke out. After it's out I exhale again to make sure no smoke remains in my oral cavity or sinuses.
- Repeat.
Hope that's somewhat helpful.
I applaud the effort here, this is more work that I have ever put into anything. Including grad school lol.
